The primary mission of Civil Affairs is to conduct civil-military operations. Civil Affairs soldiers are responsible for executing five core CA tasks, Civil Information Management, Foreign Humanitarian Assistance, Nation Assistance, Population and Resource Control, and Support to Civil Administration. Some sub tasks to these core tasks include identifying non-governmental and international organizations operating in the battlespace, handling refugees, civilians on the battlefield, and determining protected targets such as schools, churches/temples/mosques, hospitals, etc.
Civil Affairs units are the field commander's link to the civil authorities in that commander's area of operations. The soldiers make up teams which interface and provide expertise to the host nation government. USACAPOC(A)'s Civil Affairs soldiers are particularly suited for this mission since they are Army Reserve soldiers with civilian occupations such as law enforcement, engineering, medicine, law, banking, public administration, etc.
